Why does this happen?
The main cause is believed to be caused by the main logic board inside the iPhone being in constant stress. The Audio IC chip, that is responsible for the audio functionality of the iPhone is located in a part of the board that tends to flex a lot. So overtime, the chip has a fracture underneath, on a very weak trace.
